ISS Tracker API

ISS & Satellite Tracker API

ISS & Satellite Tracker API is a lightweight, high-performance REST API that provides real-time satellite tracking and orbital information for developers, researchers, educators, and space enthusiasts.

The API allows applications to retrieve the current location of the International Space Station (ISS), monitor any tracked satellite using its NORAD Catalog Number, and obtain the latest Two-Line Element (TLE) data used for orbital propagation and trajectory calculations.

Whether you're building astronomy applications, satellite visualization platforms, educational software, aerospace dashboards, GIS systems, IoT tracking solutions, or space-related services, this API provides accurate and up-to-date orbital information through a simple REST interface.

With low latency, stateless architecture, and easy integration, the API is suitable for production applications, educational platforms, research projects, and real-time visualization tools.
